GEORGE A.. SCHWEBEL AND JOHN F; SCHWEBEL, OF LANCASTER, PENNSYLVANIA.

SV/'TCrI-OPE RATING DEVICE T 0 all whom it may concern:

Be it known that we, GEORGE A.. Senwn- BRL and JOHN F. Semvnnni.,citizens of the Tnited States, residing at Lancaster', in the county ofl'iancaster and State o. Pennsylvi nia, have invented certain new anduselul lfmprovements in Switch-0perating Devices, of which thefollowing` is a speci'lication, rel"- erence being had therein to theaccompanying drawing.

Our invention relates to switch-operating devices of that class whichare used to shil't the switch-tongue on street railways, and of thatparticular class which are operated l'roni the car.

The objects of our invention are to produce simple, 1positive id durabledevice of this class and also one that may be operated from the platformof the car by the motor-man without interfering with his regular duties.lhile still another object of our invention is to provide a device olthis kind secured to the car-truck in such a way that lateral movementsotl 'the car body will in no way all'eet the operation or relation ofthe device with relation to the road bed or track.

lith these and other objects in View, our invention consists in certainnovel construction and combination of parts as will herein- I strainedby the tension spring 17, which 1s alter be fully described and claimed,reiference being had to the accompanying drawing forming part of thisapplication and in which like 'figures of reference relier tocorresponding parts in all the views. But it is 'lully understood thatwhile we have herewith described our invention herewith illustrated,slight changes may be made in the construetion and arrangement of theparts without departing from the spirit oli the invention.

1n the drawings zv-Figure 1, is a sectional elevation ol a partial viewof a car showing our device attached thereto and in a position `foroperating a switch. Fig. 2, is a -lront view of our device in detail asattached to the car-truck frame. Fig. 3, is a partial plan view of arail and switch-tongue showing the operation of our device. Fig. 4, isan enlarged top plan view of one of our switch throwing shoes. Fig. 5,is a side elevation of the same.

Referring to the drawings, 1, indicates the usual end brace o' thecar-truck, to which is secured the plate 2, which is vtorined with theoutwardly projecting arm 3, provided with the horizontal bearing L1.Mounted within said bearing 4, and the bearing brackets 5,

which are also secured to the end brace 1, are the rocker-shafts 6,which are provided with the collar 7, designed to bear against saidbearings L1, and 5, and restrict the thrust oil said rocker-sha'l'ts 6.Said rocker-shafts 6, are provided with the levers 8, which are. pivotedthereto in such a manner as to compensate lor any lateral movement olEthe cir' body, such as that produced in the act ol rounding a curve.Vilhile upon the outer ends o'l said rocker-shafts G, are rigidlysecured the heads E), at or near a central point thereof. Said heads 9,being formed with the transverse orifices 10, near the ends thereol.Hingeably secured by their upper ends within said orifices 1.0, are theliftingrods 11, to the lower ends ol which are adjustably and detachablysecured the. shoes 12, while the action of said lifting-rods 11, areguided by the bearings 13, which are 'formed in the lrame 141, which issecured to the truck end 1.

The shoes 12, are in the general lorm of a crescent with the twoengaging points 15, and are detachably secured upon the liftingrods 11,by being slipped over the end thereol and secured by tho screw 1G, whichis threaded into the end of said rod 11, while the upward movement olthe shoe is repassed through and around said rod 11, thus forming acollar, while its ends 18, are bent downward and engage orifices in theupper surface of said shoe 12, lor the purpose of keeping one ol theengaging edges 15, ol the shoe in contact with the rail so that it willreadily engage the switch-tongue when released lrom the guard rod 19, bythe lowering action ol the lifting-rod. lt may here be stated that bythe use ol a shoe of this form, when one o1 the engaging edges 15,becomes worn the shoe may be reversed to bring the other end into use.

The guard rods 19, arc lor the purpose ol keeping the shoes from contactwith the rail when not in use and are secured to the frame 14, andengage the side of the shoe when same is in a normal p osition, and alsoserve to restrain the turning action of the tension spring, and it willhere be noted that as the shoe is lowered it will extend below the topof the rail before it is released by said rod, so that it cannot swingtoo lar around to prevent its catching the rail.

The operation of the device is controlled by the connecting-rods 20,which are attached at their rear ends to the levers S, and at theirforward ends to the hand-levers 2l, Which are mounted upon thecar-platform in the usual Way and secured in a normal position by therod 22, and catch 23, Which engage the notched quadrant 24.

The operation of our device is so simple and Will be so readilyunderstood from the foregoing description that it will not be necessaryto go into the matter more fully.

Our invention having` thus been described, What We claim as new anddesire to secure by Letters Patent is l. In a switch-operating` deviceof the class described, comprising a frame secured to the car-truck andformed With vertical bearings near the ends thereof, lifting-rodsmounted in said bearings, shoes formed with reversible switch-tongueengaging ends and detachably secured upon said lifting-rods, tensionsprings secured upon said rods in contact with the upper surface of saidshoes and having` their ends detachably secured. to said shoes, meansfor raising and lowering,` said lifting-rods and means for operatingsaid raising and lowering,` mechanism from the car.

2. In a switch-operating device of the class described, comprising aframe formed With etending arms containing vertical bearings and securedto the car-truck, liftingrods mounted in said bearings, engaging shoesdetachably and adjustably secured upon said lifting-rods, guard rodssecured to said frame and adapted to co-act with said shoes and limitthe swivel action thereof, supporting bearings secured to said car-truckin a higher plane than said frame, rockerarms journaled. in said.bearings, cross-heads secured upon the outer ends of said rockerarms andprovided With orifices to receive and retain the ends of said liftinglevers, said rocker-arms formed with transverse orilices, swivel levershaving,` their lower ends rotatably secured in said orifices,connecting-rods secured to the upper ends oi" said levers and ahand-lever mounted upon the car-platform with its lower end secured tosaid connectingrod and adapted to operate the same and the mechanismthereto attached.

ln testimony whereof We aHiX our signatures in presence of twoWitnesses.
